Answer:
Ice is the solid state of water, a normally liquid substance that freezes to the solid state at temperatures of 0 °C (32 °F) or lower and expands to the gaseous state at temperatures of 100 °C (212 °F) or higher.
Explanation:
The density of the two pieces of rock is determined from the ratio of their masses to the pore volume of the rock.
<h3>What is density?</h3>
The density of an object is the ratio of mass to volume of the object.
Density = mass/volume
Assuming a constant pore volume of the rock = V
Density for 26.3 g = 26.3/V
Density for 58.3 g = 58.3g/V
Thus, the density of the two pieces of rock is determined from the ratio of their masses to the pore volume of the rock.

Answer: A forest fire could affect the geosphere by ash and the heat from the fire, but the fire would affect the biosphere by less oxygen in the air and would make it hard for human to breath affecting climate change. Also many homes to wildlife that live in the forest would lose their homes. This would result in lose of money from no hunting and that affect the economy.
